From the martyrology:
"At Chalons, in France, St. Marcellus, martyr, under the emperor Antoninus. Being invited to a profane banquet by the governor Priscus, and abhorring the meats that were served, he reproved with great freedom all persons present for worshipping the idols. For this, by an unheard-of kind of cruelty, the same governor had him burned alive up to the waist. After persevering for three days in praising God, he yielded up his undefiled soul."
